2 Part I. CA Budget Crisis
3 CA Budget Crisis w What is Happening to UC? UC Budget from the state General Fund
4 UC Budget w Econ 240A Lab Four w New data for Fiscal Year w Governor’s Budget Summary released January
UC Budget, through Fiscal Year Millions $
6 CA Budget Crisis w What is happening to the CA economy? CA personal income
8 CA Budget Crisis w How is UC faring relative to the CA economy?
UC Budget Vs. CA Personal Income, through CA Personal Income, $B UC Budget, $B
10 CA Budget Crisis w What is happening to CA state Government? General Fund Expenditures?
12 CA Budget Crisis w How is CA state government General Fund expenditure faring relative to the CA economy?
CA Size of Government Vs. CA Economy, through CA Personal Income $ B CA General Fund Expenditure $B
14 Long Run Pattern Analysis w Make use of definitions: w UCBudget = (UCBudget/CA Gen Fnd Exp)*(CA Gen Fnd Exp/CA Pers Inc)* CA Pers Inc w UC Budget = UC Budget Share*Relative Size of CA Government*CA Pers Inc
15 What has happened to UC’s Share of CA General Fund Expenditures? w UC Budget Share = (UC Budget/CA Gen Fnd Exp)
17 CA Budget Crisis w Estimate of UC’s Budget Share for : 4.25 % or 4.85% will the legislature lower UC’s share?
18 What has happened to the size of California Government Expenditure Relative to Personal Income? w Relative Size of CA Government = (CA Gen Fnd Exp/CA Pers Inc)
20 California Political History w Proposition 13 approximately 2/3 of CA voters passed Prop. 13 on June 6, 1978 reducing property tax and shifting fiscal responsibility from the local to state level w Gann Inititiative (Prop 4) In November 1979, the Gann initiative was passed by the voters, limit real per capita egovernment expenditures
21 CA Budget Crisis w Estimate of the relative size of the CA government: 6.75% vs %?
22 CA Budget Crisis: Pattern Estimate of UCBudget w UC Budget = UC Budget Share*Relative Size of CA Government*CA Pers Inc w Midpoint estimate: w UC Budget = *.0605* $B =$ 3.24 B estimate w Governor’s proposal in January: $ 3.04 B w So, $ 3.24 B is probably too optimistic
23 Econometric Estimates w Linear Trend Estimate w UCBUD(t) = a + b*t +e(t) about same as Governor’s January proposed $ 3.04 B Lucky?
25 Econometric Estimates w Logarithmic (exponential trend) w lnUCBUD = a + b*t +e(t) w simple exponential trend will over-estimate UC Budget
27
28 Econometric Estimate w Dependence of UC Budget on CA Personal Income w UCBUD(t) = a + b*CAPY(t) + e(t) w looks like a linear dependence on income will overestimate the UC Budget for
30 Econometric Estimates w How about a log-log relationship w lnUCBUD(t) = a + b*lnCAPY(t) + e(t) w autocorrelated residual w fitted lnUCBUD( ) = $3.27 B w actual (Governor’s Proposal) = $3.04B
31
32
33
34 Econometric Estimates w Try a distributed lag Model of lnUCBUD(t) on lnCAPY(t) clearly lnUCBUD(t) is trended (evolutionary) so difference to get fractional changes in UC Budget likewise, need to difference the log of personal income

41 Estimate ARONE Model for dlncapy(t) w Orthogonalize dlncapy and save residual w need to do transform dlnucbud w dlnucbud(t) = h(Z)*dlncapy(y) + resid(t) w dlncapy(t) = 0.732*dlncapy(t-1) + N(t) w [ Z]*dlnucbud(t) = h(Z)* [ Z]*dlncapy(t) + [ Z]*resid(t) w i.e. w(t) = h(Z)*N(t) + residw(t)
42
43Orthogonal residuals from ARONE Model for dlncapy
44 Distributed Lag Model w Having saved resid as res[N(t)] from ARONE model for dlncapy w and having correspondingly transformed dlnucbud to w w cross-correlate w and res
45
46 Distributed lag model w There is contemporary correlation and maybe something at lag one w specify dlnucbud(t) = h 0 *dlncapy(t) + h 1 *dlncapy(t-1) + resid(t)
47
48 Dlnucbud c dlncapy dlncapy(-1)
49 w Try a dummy for , the last recession, this is the once and for all decline in UCBudget mentioned by Granfield w There is too much autocorrelation in the residual from the regression of lnucbud(t) = a + b*lncapy(t) + e(t) to see the problem w Look at the same regression in differences

59 Distributed lag Model w Modify the specification; drop dlncapy(t) to get a forecasting model w dlnucbud(t) = h 1 *dlncapy(t-1) + dummy ( ) + resid(t)

67 Conclusions w Governors proposed cut in UC Budget of 4.8% is greater than expected from various models w The UC Budget growth path ratcheted down in the recession beginning July 1990 w The UC Budget growth path may be ratcheting down again in the recession beginning March 2001 it may be too early to tell
